[0002] During the coal mining process, a large amount of coal gangue with low carbon content and difficult to use will be mined. The coal gangue needs to be transported out of the mine and transported to the ground through mine cars, coal bunkers, belt conveyors and hoisting equipment. Among them, it is necessary to use a gangue turning device to transport the coal gangue from the mine car to the coal bunker and then to the belt conveyor.

[0029] Example 1:

[0030] A mine rapid gangue turning device, such as Figures 1-4 and Figure 6 As shown, it includes a bracket 1, which is arranged on the left side of the rail. The upper part of the bracket 1 is hinged with a first support block 2 and a second support block 4, wherein the second support block 4 is located in the middle of the first support block 2, and the lower part of the bracket 1 is hinged with two symmetrically distributed first hydraulic cylinders 3 and a second hydraulic cylinder 301, wherein the second hydraulic cylinder 301 is located between the two first hydraulic cylinders 3, and the telescopic ends of the two first hydraulic cylinders 3 are both hinged with the first support block 2, and the telescopic end of the second hydraulic cylinder 301 is hinged with the second support block 4. The right side of the support block 4 is fixed with a guide hopper 5, the right side of the first support block 2 is fixed with a mounting frame 6 located below the guide hopper 5, the mounting frame 6 is fixed with two fixed blocks 7 symmetrically distributed on the left and right and two first baffles 8 symmetrically distributed on the left and right, the front of the first baffle 8 is slidably connected to the limit block 13, the limit block 13 is fixed with a spring between the adjacent first baffle 8, the limit block 13 is used to initially limit the mine car a, the lower side of the fixed block 7 is provided with a second baffle 9, the two second baffles 9 symmetrically distributed on the left and right The symmetry axis is parallel to the symmetry axis in the front and rear directions of the mine car a in the vertical direction, which is used to ensure that the mine car a is in a stable state when it is lifted, so that the center of gravity of the whole is kept stable. The opposite sides of the two second baffles 9 are provided with arc-shaped protrusions with the same arc as the lower part of the mine car a, which are used to provide emergency support for the mine car a to prevent the mine car a from falling due to damage to the parts and smashing the rails. There are two first hydraulic cylinders 3 and a second hydraulic cylinder 301. There are gaps between the mine car a and the two first baffles 8 and the two second baffles 9 to facilitate the mine car a normally enters between the two first baffles 8 and the two second baffles 9. At the same time, due to the small gap, the impact of the gap on the mine car a during the gangue turning process is negligible. By controlling the guide hopper 5 and the mine car a separately, the mine car a is reset in advance and the mine car a is released from the limit, which is convenient for limiting the next mine car a during the process of cleaning the coal gangue, thereby improving work efficiency. The second baffle 9 on the left is provided with a lifting component for lifting the mine car a, and the guide hopper 5 is provided with a cleaning component for cleaning it and the mine car a.

[0031] like Figure 5As shown, the lifting assembly includes two first push rods 10 symmetrically distributed front and back, the two first push rods 10 are hinged to the left part of the second baffle 9 on the left, the telescopic ends of the two first push rods 10 are respectively hinged with a lifting plate 11, the lifting plate 11 is hinged to the second baffle 9 on the left, the two lifting plates 11 cooperate with the outer bottom of the mine car a, the lifting plate 11 is fixed with a shielding plate 12, the shielding plate 12 is used to limit the movement of the mine car a, and the mine car a is lifted by the contact between the two lifting plates 11 and the outer bottom of the mine car a, thereby extending the life of the wheel axle of the mine car a and improving the stability when lifting the mine car a. The second baffle 9 on the right is provided with a locking assembly for limiting the two lifting plates 11.

[0032] like Figure 1 and Figure 7 As shown, the locking assembly includes two second push rods 14 symmetrically distributed front and back, and the two second push rods 14 are both installed on the second baffle 9 on the right. The telescopic ends of the second push rods 14 are fixedly connected to the limit pins 15, and the two limit pins 15 are both slidingly connected to the second baffle 9 on the right, and the limit pins 15 are limitedly matched with the adjacent lifting plate 11.

[0033] like Figure 1 、 Figure 8 and Figure 9 As shown, the cleaning assembly includes a drive motor 16, which is installed on the front guide hopper 5 through a fixed bracket, and the output shaft of the drive motor 16 is fixedly connected to a rotating shaft 17, which is rotatably connected to the guide hopper 5, and a first mounting block 18 is fixedly connected to the middle of the rotating shaft 17, and a third push rod 19 is installed on the first mounting block 18, and the telescopic end of the third push rod 19 is fixedly connected to a second mounting block 20, and the second mounting block 20 is fixedly connected to two L-shaped rods 21 that are symmetrical in front and back, and the two L-shaped rods 21 are respectively hinged to fourth push rods 22, and the second mounting block 20 is hinged to a blanking plate 23 that is hinged to the telescopic ends of the two fourth push rods 22.

[0034] When using this device to quickly turn over the gangue of mine car a, the staff starts the first push rod 10 on the rear side through the control terminal, and the telescopic end of the first push rod 10 on the rear side extends outward. The telescopic end of the first push rod 10 on the rear side pushes the lifting plate 11 on the rear side to rotate along the second baffle 9 on the left side, and the rear shielding plate 12 rotates synchronously with the rear lifting plate 11 until the rear lifting plate 11 contacts the second baffle 9 on the right side. Then the staff closes the first push rod 10 on the rear side and opens the second push rod 14 on the rear side through the control terminal. The telescopic end of the second push rod 14 on the rear side drives the limit pin 15 on the rear side to move downward to pass through the second baffle 9 on the right side and limit the lifting plate 11 on the rear side. At this time, the staff closes the second push rod 14 on the rear side through the control terminal.

[0035] After the lifting plate 11 on the rear side is fixed, the staff moves the mine car a containing coal gangue backward along the track to this device. Since there are gaps between the mine car a and the two first baffles 8 and the two second baffles 9, the mine car a can enter smoothly without shaking significantly during the gangue turning process. During the movement of the mine car a, it contacts and squeezes the two limit blocks 13, and the springs of the two limit blocks 13 are contracted. After the mine car a passes the two limit blocks 13, the springs of the two limit blocks 13 reset and drive the two limit blocks 13 to reset. The two limit blocks 13 limit the mine car a to prevent the mine car a from moving forward. At the same time, the two limit blocks 13 cooperate with the rear baffle 12 to preliminarily limit the position of the mine car a.

[0036] After the position of mine car a is initially limited, the staff starts the first push rod 10 on the front side through the control terminal. The telescopic end of the first push rod 10 on the front side extends and drives the lifting plate 11 on the front side to rotate. The front baffle 12 rotates synchronously with the front lifting plate 11 until the front lifting plate 11 contacts the second baffle 9 on the right. At this time, the front baffle 12 contacts the mine car a, completing the limitation of the front and rear sides of the mine car a. Then the staff closes the first push rod 10 on the front side and opens the second push rod 14 on the front side through the control terminal. The telescopic end of the second push rod 14 on the front side drives the limit pin 15 on the front side to move downward to pass through the second baffle 9 on the right and limit the lifting plate 11 on the front side. At this time, the staff closes the second push rod 14 on the rear side through the control terminal. At this time, both lifting plates 11 are located on the lower side of mine car a.

[0037] After the two baffles 12 limit the mine car a, the staff simultaneously starts the two first hydraulic cylinders 3 and the second hydraulic cylinder 301 through the control terminal. The telescopic ends of the two first hydraulic cylinders 3 drive the mounting frame 6 and the parts thereon to move upward through the first support block 2 and rotate at the same time. The lifting plate 11 cooperates with the first baffle 8 and the second baffle 9 to lift and rotate the mine car a. Since the symmetry axes of the two second baffles 9 are parallel to one of the symmetry axes of the mine car a in the vertical direction, the mine car a is ensured to be in a stable state when lifted. The telescopic end of the second hydraulic cylinder 301 drives the guide hopper 5 and the parts thereon through the second support block 4 to move and rotate synchronously with the mounting frame 6 and the parts thereon. The mine car a is lifted by the contact between the two lifting plates 11 and the outer bottom, thereby extending the life of the wheel axle of the mine car a and improving the stability when lifting the mine car a.

[0038] If the two lifting plates 11 break during the process of lifting the mine car a, the arc-shaped protrusions on the opposite sides of the two second baffles 9 will lift the mine car a to prevent the mine car a from falling directly and damaging the two first hydraulic cylinders 3, the one second hydraulic cylinder 301 and the rails.

[0039] When the mine car a and the guide hopper 5 are flipped to the required positions, the staff closes the two first hydraulic cylinders 3 and the second hydraulic cylinder 301 through the control terminal. At this time, the coal gangue in the mine car a moves to the left to the prepared transfer device under its own gravity and the guidance of the mine car a and the guide hopper 5. Then the staff starts the drive motor 16, the third push rod 19 and the two fourth push rods 22 through the control terminal. The telescopic end of the third push rod 19 drives the blanking plate 23 to enter the mine car a by sticking to the right side of the mine car a through the second mounting block 20. When the blanking plate 23 moves to the bottom of the mine car a, the telescopic ends of the two fourth push rods 22 extend, so that the blanking plate 23 is always close to the bottom of the mine car a. At the same time, the output shaft of the drive motor 16 drives the third push rod 19 to rotate through the rotating shaft 17 and the first mounting block 18, and the telescopic end of the third push rod 19 retracts , so that the blanking plate 23 scrapes the coal gangue at the bottom of the mine car a and pushes it to the left, then the telescopic ends of the two fourth push rods 22 begin to contract, and the blanking plate 23 remains perpendicular to the mine car a and the guide hopper 5. When the blanking plate 23 moves to the point where the third push rod 19 is perpendicular to the left side of the guide hopper 5, the telescopic end of the third push rod 19 begins to extend, and the telescopic ends of the two fourth push rods 22 begin to extend until the blanking plate 23 completely pushes the coal gangue out of the guide hopper 5. Then the staff resets and turns off the drive motor 16, the third push rod 19 and the two fourth push rods 22 through the control terminal, and accelerates the discharge speed of the coal gangue in the mine car a through the blanking plate 23 to prevent the coal gangue from not being able to be discharged completely and affecting the subsequent loading amount. After the blanking plate 23 completes pushing the material, the staff resets the drive motor 16, the third push rod 19 and the two fourth push rods 22 through the control terminal.

[0040] After the gangue is pushed out of the mine car a by the unloading plate 23, the staff starts the two first hydraulic cylinders 3 through the control terminal. The telescopic ends of the two first hydraulic cylinders 3 contract and drive the mounting frame 6 and the parts thereon to gradually reset through the first support block 2, and put the mine car a back to its original position. Then the staff releases the limit of the two limit pins 15 on the adjacent lifting plates 11 through the control terminal, and resets the two first push rods 10, so that the two shielding plates 12 lose the obstruction of the mine car a. Then the staff moves the mine car a backward out of the device, and resets the rear lifting plate 11 and the rear limit pin 15 through the control terminal to block the next mine car a. Then the staff moves the next mine car a to the device and repeats the above operations to fix the mine car a. By controlling the guide hopper 5 and the mine car a separately, the mine car a is reset in advance and the limit of the mine car a is released, which is convenient for limiting the next mine car a during the process of cleaning the coal gangue, thereby improving work efficiency.

[0041] When the gangue in the guide hopper 5 is cleaned and the drive motor 16, the third push rod 19 and the two fourth push rods 22 are reset, the staff resets the second support block 4 and the guide hopper 5 and the parts thereon by resetting the second hydraulic cylinder 301, and directly repeats the above operation steps to process the gangue in the next mine car a.

[0042] Example 2:

[0043] On the basis of Example 1, Figure 4 As shown, an adjustment component is also included, which is used to vertically lift the mine car a. The adjustment component is arranged on the two fixed blocks 7. The adjustment component includes two groups of fifth push rods 24 symmetrically distributed on the left and right, each group includes two fifth push rods 24, and the two groups of fifth push rods 24 are respectively installed on adjacent fixed blocks 7. The telescopic end of the fifth push rod 24 is fixedly connected to the adjacent second baffle 9. The telescopic end of the fifth push rod 24 is initially in an extended state. A protrusion is provided on the lower side of the fixed block 7, and the protrusion of the fixed block 7 is slidingly connected to the adjacent second baffle 9. By shortening the telescopic ends of the four fifth push rods 24, the mine car a is separated from the rail in a vertical manner from the ground. By extending the telescopic ends of the four fifth push rods 24, the mine car a is returned to the rail in a vertical manner, ensuring that the mine car a can return to the rail normally, preventing the mine car a from having a slight deviation from the track and requiring manual reset, reducing workload, reducing work flow, and improving work efficiency.

[0044] After the two baffles 12 limit the mine car a, the staff activates the four fifth push rods 24 through the control terminal. The telescopic ends of the four fifth push rods 24 move upward and retract, lifting the two second baffles 9 and the parts thereon together. The two second baffles 9 slide upward along the protrusions on the adjacent fixed blocks 7, so that the two lifting plates 11 are between the flipped mine car a, lifting the mine car a upward for a distance, so that the mine car a is vertically away from the rails, and then the staff closes the four fifth push rods 24 through the control terminal.

[0045] When the gangue in the mine car a is cleaned, the first hydraulic cylinder 3 drives the mine car a to move vertically above the rail through the parts thereon, and then the staff starts the four fifth push rods 24 through the control terminal, so that the telescopic ends of the four fifth push rods 24 are extended to reset. During the resetting of the telescopic ends of the four fifth push rods 24, the mine car a returns to the rail in a vertical manner, ensuring that the mine car a can return to the rail normally, preventing the mine car a from having to be manually reset after a slight deviation from the track, reducing workload, shortening work processes, and improving work efficiency.
